I don't know how to quote a tweet and it is entirely possible that this has been known for a long time and I was unaware of it, but per his Twitter account he has retired. I don't know how to quote a tweet but his twitter page is here: https://twitter.com/VizquelOmar13

He tweeted it about six hours ago.

Vizquel's retirement at the end of the 2012 season got some attention from the MLB Network the last day of the regular season. The Blue Jays started hiim at shortstop, he singled in his last at bat and came out of the game defensively with two out in the ninth to give hiim a chance to walk off the field to applause. It looked like a nice way to end his Hall of Fame career.
